Abstract: A display device includes a substrate, a plurality of pixels above the substrate, each of the plurality of pixels including a first electrode, a light emitting layer above the first electrode, and a second electrode above the light emitting layer, a display region including the plurality of pixels, a first organic insulating layer located between the substrate and the light emitting layer, and a sealing layer above the second electrode and covering the plurality of pixels. The first organic insulating layer includes a first opening part surrounding the display region, the sealing layer has a first inorganic insulating layer, a second organic insulating layer and a second inorganic insulating layer, the first inorganic insulating layer and the second inorganic insulating layer cover the first opening part, a second opening part passing through the first inorganic insulating layer and the second inorganic insulating layer.

Abstract: A weak light releasing layer includes a plurality of weak light releasing sections separated from each other by overlapping with corresponding one of the plurality of light releasing sections and a second inspection portion that is positioned relatively to the plurality of weak light releasing sections and overlaps with a first inspection portion. There are a first region and a second region that differ depending on whether or not there is an overlap with the second inspection portion inside an outer shape of the first inspection portion. The first region is sandwiched between any pair of portions of the second region in any of a plurality of directions orthogonal to each other.
